United States Patent Office 3,202,946 WAVE GUIDE CONNECTOR Donald J.Newman, Needham, Mass, assignor, by mesne assignments, to the UnitedStates of America as represented by the Secretary of the Army Filed Oct.21, 1963, Ser. No. 317,852 1 Claim. (Cl. 3334-98) This invention relatesto wave guide connectors and more particularly to a quickconnect-disconnect wave guide connector.

Wave guides comprising more than one section require a connector betweenthe adjoining sections. Standard wave guide connectors comprise a flangeand a choke held in mated cont-act by a plurality of bolts or welds. Thepresent invention comprises a wave guide connector wherein the choke isprovided with threaded apertures and the flange is provided with slotsmatching the apertures of the choke. In this way bolts threadably heldin the choke may be lefit in place and connection made by sliding theflange into mating contact with the choke and threadably tightening thebolts. One or more slots may be replaced by an aperture, as describedbelow, to insure a secure connection.

It is therefore an object of the present invention to provide a waveguide connector that may be quickly and easily connected ordisconnected.

It is a further object of the present invention to provide a wave guideconnector which provides for reduction in wear on the threads of theconnecting bolts upon repeated connections and disconnections of thewave guide sections, thereby allowing the flange and choke to mate moreaccurately and lengthen the bolt life.

These and other objects of the present invention will become moreapparent from a consideration of the following description and drawingswherein:

FIGURE 1 shows an exploded view of the connector with three of the boltsin place in the choke; and

FIGURE 2 shows a perspective view of the connector in the connectedposition with all bolts in place.

A wave guide connector comprising a flange and a choke 12 is shown inFIGURE 1. Flange 10 comprises a generally rectangular plate 18 havingparallel slots 29 disposed adjacent three of the four corners of theplate. A hole 22, for receiving a securing bolt 34, is disposed adjacentthe fourth corner of plate 18. Choke 12 comprises a generallyrectangular plate 24 having four threaded apertures 26 adjacent each ofthe tour corners of the plate and matched to slots 20 and hole 22 ofplate 18. Plate 1 8 and plate 24 each carry a portion of the \wave guide28 and 30, respectively, to be connected as shown in FIGURE 2, whereinthe broad faces 14 and 16 are disposed in mated contact. Wave guide 28is connected to wave guide 30 by slidalbly mating face 14 of plate .18to face 16 of plate 24 and simultaneously engaging slots 20 in plate 18with bolts 32 in plate 24. Bolts 32 are permanently engaged in .plate 24and need only be threadably tightened to hold plate 18 in contact withplate 24. 'An additional bolt 34 is then inserted through hole 22 inplate 18 and threadably secured to plate 24 to insure a rigid connectionbetween the two plates.

Obviously many modifications and variations of the present invention arepossible in the light of the above teachings. It is therefore understoodthat within the scope of the appended claim the invention may bepracticed otherwise than was specifically described.

I claim:

A connector for two highly conductive waveguide sections, each sectionhaving a central longitudinal axis: said connector including a firsthighly conductive end flange on one of said sections and a second highlyconductive end flange. on the other section; a plurality of studs onsaid first flange, each stud being parallel to the section axis; aplurality of open ended slots in said second flange, said slots beingequal in number to said studs, with all of the slots being parallel andtransverse to the section axis; a threaded perforation in said firstflange parallel to the section axis; a perforation in said second flangeparallel to the section axis; and a threaded connector insert-ablethrough the second perfioration and engaging said first perforation,upon traversing engagement of said slots and studs.
